The propane industry should get back to its roots of servicing and selling appliances to residential customers if it expects to increase the industry's sales, writes Randy Doyle, chief financial officer of Blossman Gas. Propane marketers have focused too much on the autogas segment and on mergers and acquisitions to expand their business and have gotten "off track from what built the industry," he writes. "[M]ore propane marketers need to sell and service appliances," Doyle adds.
